Q: What's the best valued GPS to buy?

I'm looking to buy a GPS for my parents-in-law for xmas. I need to find one that isn't too gimped on the features but is pretty easy to use. They are not total beginners with technology, but they aren't too good with it either.

Lifetime map updates means they can always have updated roads and Points of Interest without paying (the updates used to be in the neighborhood of $100/pop)

Lifetime traffic means they can always have the traffic features without ever having to pay for a subscription. If one freeway is congested, it'll determine if you're better off hopping onto a side street or pushing through on the freeway. Pretty cool.

5" screen should ensure that they can read what it's saying and see enough of the map to know what's going on.
